Strangers can not contact you, can not add you to groups, can not call you, communication code is a 4 digit code thats generated by your app and the same is required for anyone trying to reach you, they can connect you only if they enter the code of yours. This code is one time use only and refreshes as soon as one is consumed. You can disable this to allow chats/calls from everyone if you choose to.
